Well, the article isn't clear on that:
It's also not known whether the next trilogy of Star Wars films to hit the screen will be the one being developed by The Last Jedi writer/director Rian Johnson or the one that has been assigned to Game of Thrones showrunners David Benioff and D.B. Weiss — or something yet to be announced.
Johnson's trilogy was the first to be announced, so I would guess it's that, but we can't be sure.
